Put another way, in principle you should be able to take an XML ASCII
encoded text message and send it over an RS-232 link that uses Start of text
and End of text for it's own framing. If you did that, you don't want those
characters in your XML data.

You "should" also be able to store a binary image, or zip file or a JSON document unchanged as XML Text content.
But you cant.
Thats just the way it is.
We can argue until the cows come how about "why" and "should" ...
It is historically interesting, but in practice what is really necessary to know is "what" not "why".
And then you can do fun stuff like
<text><soh/>X<eoh/><ff/>My RS232 Text<lf/></text>
